Candy · MARS Series Vending Machines
The vending machine is rejecting coins because the controller is set up for a different type of coin mechanism than what is installed. This mismatch prevents proper operation.
Click steps to track your progress.
Use MODE 2 (Service Mode) and selection button #8 to check the coin mechanism configuration.
Ensure the configured coin mechanism matches the installed unit.
If mismatched, reconfigure the controller or replace the coin mechanism.
